Python / C API：创建＆＃34; __ all __＆＃34;对象

Question

使用普通Python3制作Python模块/库时，我可以轻松创建__all__列表。然后，我可以通过＆＃34; MODULE。__all__＆＃34;导入模块后。

然而，当通过Python / C API创建模块时，我无法找到一个简单的或者＃34;正确的＆＃34;制作__all__的方法。我查看了官方文档但未找到答案。

在使用Python / C API创建的模块中是否有简单的方法或标准方法来创建__all__？

我能够使用下面的代码创建类似的对象（例如__author__）。

static const char __author__[32] = "Devyn Collier Johnson";
static const char __copyright__[8] = "LGPLv3";
static const char __version__[16] = "2015.11.21";
PyModule_AddStringConstant(m, "__author__", __author__);
PyModule_AddStringConstant(m, "__copyright__", __copyright__);
PyModule_AddStringConstant(m, "__version__", __version__);

下面是我的特定模块的代码（我删除了函数和大块注释以便于阅读）

#include <Python.h>

#include "geometry.h"


static const char __author__[32] = "Devyn Collier Johnson";

static const char __copyright__[8] = "LGPLv3";

static const char __version__[16] = "2015.11.21";

static const char __all__[16][32] = {
    // Distance
    "distance",
    "linelength",
    // Area
    "areacircle",
    "areasquare",
    "areasquare_int",
    "areasquare_shape"
};


// Docstrings

static char module_docstring[32] =
    "Geometry Equations";
PyDoc_STRVAR(geometry_distance_docstring,
    "distance(location1: tuple, location2: tuple) -> float\nReturn the distance between two points");
PyDoc_STRVAR(geometry_linelength_docstring,
    "linelength(location1: tuple, location2: tuple) -> float\nReturn the length of a line (given two points as tuples with two floats each)");
PyDoc_STRVAR(geometry_areacircle_docstring,
    "areacircle(radius: float) -> float\nReturn the area of a circle (float)");
PyDoc_STRVAR(geometry_areasquare_docstring,
    "areasquare(length: float) -> float\nReturn the area of a square (float)");
PyDoc_STRVAR(geometry_areasquare_int_docstring,
    "areasquare_int(length: int) -> int\nReturn the area of a square (int)");
PyDoc_STRVAR(geometry_areasquare_shape_docstring,
    "areasquare_shape(square: float) -> float\nReturn the area of a square (float)");
